Back to Norfair - For the Ice Beam
Drop down from the lift and take the first door on the right. Make your way to the area marked in the screenshot (by Samus' logo). Save your game on the way if you wish.
Traverse the ledges above you with help from power grip. Proceed to the door on the far right side of the room. Climb the ledges in the next section and enter the first door above you on the left. The next room contains a series of small platforms. Leap across the platforms with help from power grip (avoid the harmful pool below if possible).
Enter the next room and find a Chozo statue holding your next power-up. It's the ice beam, an enhancement to your primary weapon. You can use it to freeze enemies in place; the enemies can then be used as platforms to reach otherwise unattainable areas.
Instead of using the door to the right, go underneath the statue and set a bomb to open a route left. Use power grip to grab hold of the pillar or freeze the enemy with the ice beam. Enter the left door into the next section. Before ascending this vertical area, enter the door on the left to find a save game room.
You'll soon notice that there aren't many platforms above you--but there are enemies! Use your ice beam to freeze the enemies in place and use them as new platforms to continue your ascent up this vertical shaft.
At the top, enter the door on the right. Traverse this area using power grip and ice beam (you can freeze the enemies that appear from the pool below). Leap from a frozen enemy into the hands of the Chozo statue, which provides guidance to the next power-up location. It reveals the route to Kraid.
Continue to the right using your ice beam to turn your enemies into frozen platforms. Enter the door at the end. The next room is more of the same. Leap to the small platform and use the ice beam to freeze the moving enemies. Freeze one close to your platform, stand on it, then freeze the other enemy so you can jump to the next ledge.
In the right side of the room, freeze the upper enemy. Bomb the second block down from the ceiling to expose a hidden missile tank. Drop down and continue through the door on the right side.
Walk to the right side of the next chamber to fall through a hole. Drop down to the very bottom of this shaft and enter the door on your left. You're back in the initial room that required the power grip to navigate.
As you move to the left, spot the enemy underneath the row of blocks. He looks like he's trying to get out! Bomb the floor to allow the enemy to soar higher. When the creature is at its peak, shoot it with the ice beam. Jump onto the creature and find a ledge above. Jump to the ledge, walk to the right, and snag the missile tank.
Exit this chamber to the left and use the save game room if you wish. Exit to the left. You're underneath the Brinstar lift here. Use your ice beam to freeze the enemies. Use them as platforms to reach the lift. Return to Brinstar.
